disposed of above the, sluice f or the actuating 5 gears is very small.

It is besides necessary to avoid any groove in the walls of the sluice to obtain the best possible coefficient of outow i The. present invention has for its object, a device which is meant. to. fulll entirely these conditions. i

The annexed drawings. show', by way of example only, an embodiment of the object of the invention. L

Figures l `and* 2 are. longitudinal sections through the sluice with the gate in closed position in full lines, and in open position in dash and dotted lines. y

Fig. l corresponds to a ilow from-right to left of thedrawings andFig. 2 to a llow in the oppo- Fig. 4 is a partial vhorizontal cross sectionA according to the lineIV-IV of Fig. 3.

1 represents the gate'itself which is preferably made of built-up iron work; its two edges 2 and 3 of cylindrical shape forming, alternately, a hinge in bearings 4 and 5 incorporated in the masonry The gate 1 is moved by screwthreaded rods 6 and 7 iixed to the gate by means of the pins 8. These threaded rods with multithread, mesh with nuts 9 and 10`held in the housings 11 and 12, which are fixed to the'masonry 40 by means of the bearings 13 and 14. Double thrust ball bearings 15 transmit the thrust of the nuts 9 to the housings 11 and similar double thrust ball bearings 16 transmit the thrust of the nuts 10 to the housings 12. Sleeves 1'7 and 45.18 protect the screw threaded rods 6 and 7 and are made tight on thenuts 9 and 10 by stuffing boxes 19 and 20. Y'

vEach nut is driven by bevel gears 21 through an adjustable coupling 22 by `a servo-motor, 23.

At the ends of the bearings 4 and 5 are located cylinders 24 with pistons 25, the ends of the pivot rods 26 passing into corresponding.

holes 27 in the edges of the gate.` (In Fig. 3, the left-hand cylinder 24 is shown removed* and .carried outside and lower so as to show the mechanical connection between Vthe correspondpushed out of a hole 27,'and loosened when the ing piston 25 and the coupling 22` ofA the ser-vomotor moreclearlyl.. By 'means of a `lever 2:8, and rod 29 each-piston 25 actuates a coupling 22, Y Which is switched in when thepivot rod V26 is pivot-rod 26 is moved into the hole 27.. The movement of the piston -25 is controlled by the slidevalve 30 and that. of the servo-motor 23 by the slide valve 31. The lever 32 combined with a rod 33. holds the Vslide valve' 31-.in itsv rest positioniwhen the pivot rod 26 moves. into the holev 2'7. of the edge of thegate. Oil under pressure produced'by a pump (notshown on the drawings). is

`delivered by a. main pipe 34, and a return Vcon-.-

duit -to the pump collects they oil issuing from the 70 different exhaust conduits 35.

The mechanical connection A28",` 29, the'valves 30, 31 and the organs connected to them are repre,- sented on the left sidepf Fig.' 3 only, but, itfis plain thatfsimilar Vdevices areconnected with the othespistons 25j and servo-motors.`

The movement of the gate is controlled 'in the following manner:

When the" gate. 1 ,is in its open position, as

shown in dash and dotted lines in Fig. 1, the pivot V80 f I rods 26at the end'soi its edges 2 "and'13 are engaged'intouthe holes27. In ordert shut the' gate, thel servo-motors of' housings 11 *are moved,` and the corresponding-couplings' 22 of thesaid housings have to be switched in afterfthepivot rods 26 at the edge 3 have been disengaged.` By unscrewing the rods 6 outof their nuts 9, `the gate turns around its edge `2. vIn orderto getl this motion, the slide valves 30 are rstoperated': to disengage thepivot rods 26; when this first motion is nished, the couplings 22 are switched in andthe slide valve 31 isffreed so that it can move, and the servo-motors are actuated to shut f the gate. The screwthreads being reversible, and the couplings'22 of the housings 12 being loose, the screw threaded rods '7 follow the movement of the gate, and turn idly in their nuts 10. They stopping of the servo-motors 23 at a suitable moment permits holding vthe gate 1 in any intermediate position or in its closed position. The opening ofthe gate is eected in a similar wry till it reaches lits uppermost position as markedin dash and dotted lines in Fig. 1. The ow is thus possible from right to left for any possible position of the gatey along completely even Walls without any interruption thereof. The tightness maybe secured along both edges 2and 3 and along the edges'in the vertical plane by means of the usually utilized devices.

shutting the sluice.

timeY possible to switch couplings 22 of the housings 12, thus withdrawing the pivot rods 26 from the holes 27 of the edge 2, engaging the pivot at the edge 3, and disengaging at the same time coilplings 22 of the housings 11. The gate remains in its open position. When the .water ows from the left tof the right, the servomotors 23 of the housings 12 may be actuated in the same manner as hereinabove described, so that the gate 1 can take the position represented in Fig. 2, thus It can valso take, of course, any intermediate position.

A gate is actuated by at least two symmetricaln ly disposed gears, which are of course moved synv the' height ofthe sluice.
